Title: Surface acoustic wave element
Inventor: NAKAHATA HIDEAKI
IPC: H03H9/25
Filed: 1991-09-26
Abstract: PURPOSE:To reduce the propagation loss of surface acoustic wave by using a substrate made of a seed crystal to form a diamond film having a predetermined crystalline. CONSTITUTION:Anisotropic etching is applied to a silicon substrate 1 to form holes 3 having an inclined (111) surface for developing a seed crystal. Diamond seed crystal particles are screened onto the (111) surface of this hole 3 to form a seed crystal 4 thereon. Further, on substrate 1, a diamond film having (111) crystal structure is developed, on which a thin piezoelectric film, a pair of electrodes, and so on are laminated to form a surface acoustic wave element. With the use of this thin diamond film having the (100) crystal structure, a highly efficient surface acoustic wave element can be obtained that causes no scattering of surface acoustic wave due to the discontinuity of grain boundary and that reduces the propagation loss of the surface acoustic wave.

Title: Automatic distributing apparatus
Inventor: HONDA HISASHI
IPC: B65G43/08
Filed: 1985-11-05
Abstract: PURPOSE:To eliminate the need of resetting of the apparatus even if the sample size is different and prevent the reduction of the detection precision by installing a means which measures the size of the material and detects the distribution object part of the material through noncontact. CONSTITUTION:When the whole or a part of a material M1 passes through a transfer part M2, the time starting from the passing through the first detection part M3 to the completion of passing is calculated in a material passing time calculating means M5. A dividing means M6 performs the division for the time calculated by the calculating means M5, with a desired distribution rate for the material M1 which is previously set or input by other means. After the lapse of the time divided by the division means M6 after the material M1 passes through the second detection part M4, a distribution part detection means M7 detects the part of the material M1 for which the signal of the second detection part M4 irradiates is detected with the time as parameter.

Title: Position detecting device
Inventor: TAKAGI JUNICHI
IPC: G01B11/00
Filed: 1987-09-30
Abstract: PURPOSE:To accurately detect the position of a moving body without prescribing the gap between a detection head and the surface of the moving body strictly by converting light from a light source and projecting laser light with a specific beam diameter on a mirror surface body provided in a specific position of the moving body. CONSTITUTION:This detecting device consists of an optical means 5 which converges the light from the laser diode 11 and projects the light with the specific beam diameter on the stage 1 of a machine tool, the mirror surface body 2 which is provided in the position where the light from the means 5 is projected and has a reflecting slanting surface 2a slanting by an angle theta deg. from the surface of the stage 1, etc. Then when the light beam is projected on the surface of the mirror surface body 2 by the optical means 3 and all reflected by the reflecting slanting surface 2a [A position in figure (a)], constant intense light is obtained and when the light reaches the side part of the reflecting slanting surface 2a (B position), the reflected light level decreases gradually as the stage 1 moves. Therefore, the position of the moving body is detected by a photodiode 18 and a signal processing part 4 according to variation in the reflected light level. Further, the diameter X of the light beam has a little variation, so the gap between the means 3 and stage 3 need not be prescribed strictly.

IPC: G03G15/08
Filed: 1985-11-05
Abstract: PURPOSE:To obtain a visible image from any of reflection and transmission type photosensitive materials by processing with the same processing soln. by making the processing time of the latter longer than that of the former. CONSTITUTION:When an internal latent image type silver halide direct positive photosensitive material is passed through a series of processing stages to obtain a positive image,the display on a magazine contg. the photosensitive material is automatically read with an apparatus to judge whether the material is of transmission type or of reflection type. In a uniform exposure stage, the quantity of light and color temp. are changed according to the judgment. Even in case where photosensitive materials of the same type are continuously exposed, the conditions may be regulated so as to obtain an image of a fine finish. In the following development stage, the speed of transfer in a processing tank is changed so that the processing time of a transmission type photosensitive material is made 1.2-2 times as long as that of a reflection type photosensitive material. A fresh soln. replenished for the transmission type one is made 1.1-2 times as much as that replenished for the reflection type one. The amount of a fresh soln. replenished in each of the following bleaching, fixing and stabilization stages is also changed according to the type. By this method, the processing conditions are automatically changed over and a photographic image of high quality is obtd. from any of reflection and transmission type photosensitive materials.

Title: Discharge register
Inventor: NOZUKI MITSUYUKI
IPC: H01T4/08
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce a voltage drop caused by the leakage current of a lightning arrester and eliminate the danger of electric shocks even if humans come into contact by connecting, in parallel with each end of a discharge registering circuit, a linear resistor having a resistance value such that the leakage current of the lightning arrester can be grounded. SOLUTION: If a leakage current flows from a lightning arrester, a current flows from the H to E terminals of a discharge-register case 1. Then the impedance of a first nonlinear resistor R1 is as high as tens to hundreds of KΩ. A linear high resister 4 has a neon tube 5 connected thereto and allows almost no current to pass through it. By selecting a linear medium resistor 2 at around 100Ω, the leakage current almost entirely flows through this resistance and its voltage drop can be determined. Should the resistor 2 be damaged, a voltage determined by the impedance of the resistor R1 is applied to the neon tube 5 to cause a discharge so as to enable this failure to be announced without affecting the counting action of a discharge registering circuit T.

Title: Composite armoring plate comprising composite layer and metal layer
Inventor: PEETAA BURIYUININKU
IPC: F41H5/04
Filed: 1992-09-18
Abstract: PURPOSE: To reduce surface density and weight by setting the Brinell hardness of a metal in a metal layer to a specific value or less. CONSTITUTION: In a composite armoring plate comprising a composite layer being composed of fiber and a polymer matrix and a metal layer, the Brinell hardness of metal in the metal layer is set to 75 HB or less, preferably 40 HB or less. The metal used in the metal layer is preferably ore with small specific gravity, such as aluminum and aluminum alloy.

IPC: H04N1/44
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To strengthen security against tapping by sending a ciphering text through a telephone line or the like. SOLUTION: When a transmitter side 1 transforms a plain text P to a ciphered text C at a ciphering transformation section 11, a key selection section 13 changes a ciphering key table at random in the unit of jobs for ciphering. Since the ciphering key table is optionally changed in the unit of jobs, even when ciphering data of the same line undergo tapping for a long period, it is difficult to analyze the ciphering method.

Filed: 1988-10-05
Abstract: PURPOSE:To impart water resistance to the pattern made of urea which is soluble in water by coating the surface of the pattern made of urea with a mixture composed of toluene and methyl ethyl ketone having water resistance. CONSTITUTION:The surface of the pattern made of urea is coated with the corrosion resistant and water resistant mixture composed of the toluene and methyl ethyl ketone. The toluene and methyl ethyl ketone solidify to form a water resistant layer after this coating.
